ELIJAH F. RESER, OF ORONOGO, MISSOURI.

COMBINED FURNACE, BOILER, AND EllAPORATlNG-PANS.

SPECIFICATION forming part of Letters Patent No. 309,096, dated December9, 1884-.

Application filed August 25, 1884.

To all whom, it may concern:

Be it known that l, ELIJAH F..REsnR, a citizen of the United States,residing at Oronogo, in the county of Jasper and State of Missouri, haveinvented certain new and useful Improvements in Combined Furnace Boil-.manipulating sugar-bearing canes and the sirups thereof; and itconsists, mainly, in the peculiar arrangement of the evaporating-pan,the steam-generator, and the heater,whereby the latter suffices togenerate the steam for driving the cane crushing machine, (not shown,)and for heating the evaporating-pan.

It consists, further, in certain details of construction, as will behereinafter more fully described and claimed.

In the drawings, Figure l is a plan View; Fig. 2, a side elevation Fig.3 is a vertical longitudinal section of the furnace, evaporating-pan,and boiler constructed according to my invention.

The side plates or castings areformed alike, and are connected at theirforward ends by the front plate, 13, and at their bottom edges by thegrate O and flue-plate D, the latter being extended horizontally fromthe rear edge of the grate rearwardly to the back of the framing underthe uptake or smoke-stack E,

in which I arrange a damper, E, for the purpose of regulating the draftand heat. The flue-plate next the grate is deflected upward, and extendsthence about parallel to and near the upper edge of side plates, A, soas to contract or reduce the vertical dimension of the horizontal flueD, in order that the heat therein may better act on the evaporating-panF, which is placed over and forms the upper wall of the said flue, asmost clearly shown in Fig. 3. The flue D extends the full width of thespace between the side plates. Thus the heat comes in contact with theentire bottom of the pan, and acts thereon in a more effective man (Nomodel.)

ner by reason of the contracted vertical area of the flue beforereferred to.

I The grate 0 may be of any desired construction suitable for thepurpose, and I provide the front plate, B, with doors B B suitablydisposed to permit the firing of the furnace Gor the removal of theashes. The boiler G is arranged between the forward ends of the platesA, above the furnace O, and preferably of alength about equal the lengthof the grate O. I preferably form this boiler with an offset or chamberG, depending from its rear side into the furnace G, and provided withfire-tubes G", for the purpose of facilitating the generation of steam.

In order to firmly and securely retain the boiler in place I lap theupper edges, a, of the plates A on opposite sides of the boiler andconform same thereto, as shown in Figs. 1 and 2, whereby the boiler willbe firmly braced and held to its place. This lapping of the side plateson opposite sides of the boiler also serves to retain the heat therein,and consequently enables the keeping of a proper steam-pressure withless heat than would be otherwise necessary. A suitable pipe, 9,conducts the steam from the boiler to the engine driving thecrushing-mill, which engine and mill are arranged in close proximity tothe boiler, and may be of any approved pattern. Illustration and detaildescription of said parts seems unnecessary. The evaporating-pan F ispreferably removably seated on the plates A A over the flue D, andbetween the boiler and the uptake. The bottom of the pan is divided bytransverse partitions f, extending alternately from opposite sides ofthe pan almost to the other side,leaving spaces f, connecting theadjacent divisions. By this construction the sap is caused to flow fromopposite sides of the pan back and forth from the point where it is fedinto same by pipe II, leading from the crushing-mill to the discharge h,thoroughly evaporating same, as shown. It will be noticed that theforward end of the pan is over the hottest portion of the furnace,

and is subjected to the greatest and an intense heat.

Experiment and practice have demonstrated that as sorghum and similarsaps advance from one stage to another less heat is required to raisethem to a boiling-point. It has also been found that the discharge endof the pans,

- where they are subjected to a uniform heat,

because of the excess of heat at such points will scorch and burn thesap. By my arrangement it will be noticed the sap is subjected to thegreatest heat at the point where first fed into the pan, and the degreeof heat to which the latter is subjected gradually decreases ,toward itsdischarge end, thus giving uniform and satisfactory results.

By my convenient arrangement it will be seen I, by means of the samefurnace, genearranged over the lateral flue, and a steamgeneratorarranged over the furnace, all arranged substantially as and for thepurposes specified.

2. The herein-described improvement in evaporators,consisting of theplates AA, connected at their forward ends, and provided with a grate,C,'forming a furnace, C, the steam boiler or generator arranged over thefurnace O, and having the upper edges of the plate A lapped on andconformed to the op.- posite sides thereof, flue D, extendedhorizontally from the furnace, with its upper end approximately flushwith the upper edge of plate A, the uptake arranged at the rear end ofsaid flue, and the pan mounted on the side plates over the flue D, andextending between the boiler and the uptake, and having its receivingend arranged next the boiler and furnace, and its discharge end next theuptake, substantially as set forth.

In testimony whereof I- affix my signature in presence of two witnesses.
